PRO2A LEFT HAND 18" 400 Legend 1/16 Carbine Length NR Side Charging Melonite M-LOK AR-15 Upper Kit

Product Description

Maximize your medium-range knockdown power, terminal velocity scaling, and straight-wall compliance variables on standard AR-15 platforms with mirror-image ergonomics and advanced side-charging operation. The PRO2A LEFT HAND 18" 400 Legend Carbine Length Non-Reciprocating (NR) Side Charging Upper Kit provides an all-inclusive rifle completion package engineered specifically to handle the structural feeding requirements and robust case expansion dynamics of Winchester's 400 Legend hunting cartridge—optimized explicitly for left-handed operators. Built with an ergonomic right-side charging handle that remains stationary while firing and a left-hand ejection port, this upper allows shooters to maintain their sight picture, clear disruptions smoothly, and keep escaping gases and spent brass completely away from their face. The setup houses an 18-inch 4150 CMV medium profile barrel with a stable 1:16 twist rate to ensure maximum stabilization and maximum downrange kinetic force for heavy hunting loads. This turn-key 16"+ kit comes fully configured with everything required to finish your rifle build: the complete side-charging upper receiver assembly, premium left-handed side-charging Bolt Carrier Group (BCG), full lower parts conversion kit, and an adjustable stock assembly. Drop these components into your standard stripped lower receiver to finish your ultimate left-handed straight-wall deer or hog tracking hunting rifle.

Key Features

• True Left-Hand Ergonomics: Mirror-image billet design pairs right-side non-reciprocating charging handle mechanics with left-hand spent case ejection to provide full comfort and safety for southpaw shooters.
• Non-Reciprocating Side Charging Action: Billet-machined right-side charging handle provides superior mechanical leverage and remains stationary during live fire cycles, protecting the shooter and saving space under large hunting optics.
• Turn-Key 16"+ Rifle Build Setup: No piecemeal component tracking required; arrives complete with a left-handed side-charging upper assembly, specialized left-hand bolt carrier group, full lower parts kit, fire control trigger group, and a standard adjustable rifle stock assembly.
• High-Impact 18-Inch Caliber Platform: Extended barrel length maximizes velocity scaling and downrange terminal energy output compared to standard length options, perfect for demanding straight-wall big game hunting setups.
• Specialized Straight-Wall Feed Optimization: Recoil and loading parameters are cleanly managed via a single large feed ramp configuration inside the receiver frame to combat case feeding friction.
• Resilient Free-Float M-LOK Architecture: Premium 15-inch slim profile aluminum rail isolates the barrel from external handling pressure vectors, ensuring continuous point-of-impact accuracy.
• Liquid Bath Nitride Protection: Full interior and exterior QPQ Melonite barrel coating provides maximum resistance to heat friction, extreme weather elements, and throat erosion.

Why Choose This Product?

Hunting within strict straight-wall restricted zones often introduces feeding friction and cycling hesitation when running unoptimized standard AR setups—an issue amplified for left-handed marksmen forced to use right-hand platforms under large hunting scopes. Pro2A Tactical eliminates these structural variables entirely. By marrying a clean left-hand non-reciprocating side charging layout with an extended premium 18-inch Melonite barrel, a robust left-handed cartridge-matched bolt carrier group, and an all-inclusive lower receiver completion parts bundle in one cohesive package, you secure consistent sub-MOA groupings, uncompromising component integration, and professional reliability built right here in the USA.
